SERPINA3 and stroke disorder: SERPINA3 was positively correlated with ABC/2 scores (P < 0.001; Table 1) and NIHSS scores (P < 0.001; Table 2) and negatively correlated with GCS scores (P < 0.001; Table 3) after adjusting for the time between stroke onset and blood collection, as well as other potential confounding factors (all P < 0.001).
